| Abstract |
The U.S. EPA, EMA, and CARB agreed to pursue an experimental data driven program to determine PEMS bias and precision measurement errors expected in in-use NTE testing and compliance before enforcement. The idea is to combine these errors into a measurement allowance which will be used with the EPA in-use regulatory standard. The combination, in-use standard plus measurement allowance, will allow for a larger threshold due to instrument and measurement uncertainties that the engine manufacturers must comply with. The gaseous PEMS measurement allowance program was completed by SwRI in April of 2007, and this work focuses on the PM-PEMS measurement allowance, as set forth in Test Plan and meeting minutes, shown in Appendices A and B, respectively. |
